Fault finding - Configurations and programming87B
Functions available and operating mode
–Deadlocking (CF009)
This function enables you to disable the interior door opening control. This function is activated by a second locking
request from the key or the electric central locking switch.
This function is only available on vehicles fitted with a top of the range UCH.
–Hazard warning lights activated by ABS (CF024)
This function is available for all countries except Brazil, Finland, Great Britain, Japan and Sweden.
For Brazil, Great Britain, Japan, Sweden and Finland configure NONE.
For other countries, configure WITH.
In the event of braking causing rapid deceleration, the ABS computer transmits an activate hazard warning lights
request via the multiplex network to the UCH.
–New vehicle storage mode (LC041 New vehicle storage mode)
If this mode is activated, consult the command, see LC041 "New vehicle storage mode" and contact the Techline.
–Daytime running lights
This configuration automatically activates the side lights and dipped beam headlights when the engine is running,
without the driver using the lighting controls.
To be used in accordance with legislative requirements.
CF031 Calibration:
When replacing the UCH computer, perform this configuration.
This command lasts approximately 30 seconds.

1.DEF : Internal electronic fault
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the ignition is switched off and back on.
If the fault is stored, clear the fault, switch off the ignition and disconnect the F8 (15A) fuse of the UCH supply
(component code 645) on the passenger compartment fuse and relay box (component code 1016).
–Refit the fuse and switch the ignition back on.
–Request locking and then unlocking, then start the engine.
Check the condition and connection of the PE1, PE2 and PE3 connectors of the UCH (component code 645)
(tabs pushed back, oxidised, broken).
If the connector(s) are faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check for + after ignition feed on connection AP43 of component 645.
Check for + accessories feed on connection SP2 (for vehicles fitted with a manual gearbox) or SP15
(for vehicles fitted with a sequential gearbox) of component 645.
Check for earth on connection NAM of component 645. Check the earth on connection MAM of component 645.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault reappears as stored, contact Techline.
If the fault does not reappear, switch the lighting, wipers, vehicle locking and climate control request controls on
and off several times, then read the faults again.
If the fault is still present. Do not operate on the computer, contact Techline.
AFTER REPAIRIf the computer has been replaced (at the request of the Techline): reconfigure the new
UCH (see Configurations and programming).
Deal with any other faults.

Check that LC096 "Automatic wiper function" displays "With". If not, carry out CF194 "Automatic wiper
function".
Check that LC095 "Automatic headlight function", displays "With". If not, carry out CF193 "Automatic
headlight function".
Check the condition and the positioning of fuses F2 (15A), F8 (15A), F19 (5A), F27 (5 A) depending on the
equipment and F29 (15A) on the passenger compartment fuse and relay box (component code 1016).
